PAPER-MAKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 587,918, dated August 10, 1897.

Application filed August 4, 1896. Serial No. 601,593. (No model.)

T0 all whom, it may concern:

Be it known that we, GEORGE L. BIDWELL, of Warren Papermills, in the county of Hunterdon and State of New Jersey, and SAMUEL C. REYNOLDS, of Coinstocks Bridge, in the county of New London and State of Connecticut, have invented certain new and useful Improvements in Paper-Making Machines, of which the following is a full, clear, and exact description.

The object of the invention is to provide certain new and useful improvements in cylinder paper-making machines whereby a perfeet couching of the paper-pulp takes place and all Waste and loss of pulp are entirely prevented and the deckles can be readily adjusted for any desired width of paper while the machine is in motion.

The invention consists of certain parts and details and combinations of the same, as will be fully described hereinafter andthen pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar charactersof reference indicate corresponding parts in all the figures.

Figure 1 is a plan view of a vat and cylinder-mold mounted therein and having the improvement applied. Fig. 2 is a cross-section of the same on the line 2 2 of Fig. 1. Fig. 3 is a side elevation withthe vat omitted and showing the couch-roll and coucher-felt. Fig. 4 is a cross-section on the line 4 at of Fig; 3, with the cylinder-mold in dotted lines and showing the deckles adjusted for narrow paper. Fig. 5 is an end elevation of the same with the deckles adjusted for wide paper. Fig. 6 is a sectional side elevation of the cylinder-mold and deckles and deckle-shifters. Fig. 7 is an enlarged cross-section of the same. Fig. 8 is a side elevation of the packing for the deckle-shifters, and Fig. 9 is an enlarged section of the same.

The improved cylinder paper-making machine has the shaft A of its cylinder-mold A journaled in suitable bearings A in vertical slots in the framework 13, arranged in the vat B. The slots in which the bearings of the cylinder-mold are mounted form outlets through which the water from the cylinder can pass. The cylinder-mold A is engaged face of the flange F on part of its periphery by two deckles C 0, made in the form of endless rubber bands, with the, face of the band next to the cylinder-mold A of soft or spongy rubber, while the reverse side is composed of a harder and smootherrubber. (SeeFig. 7.) The deckles O C extend around the sides and bottom of the cylinder-mold A, so as to-leave the top portion of the cylindermold free forthe couchroll D, around which passes a felt E, in the usual manner. (See Fig. 3.)

Now it is evident that by the arrangement described the deckles do not pass between the cylinder-mold and the couch-roll, so that the latter is free to perfectly couch the paper pulp on the cylinder-mold.

Each of the deckles C and C passes with surrounding the sides and bottom of the cylinder-mold A, as plainly indicated in the drawings, said deckle-shifter supporting at its upper ends pulleys G G, over which pass the upper parts of the deckle, the outer run of which also passes over a pulley G and idlers G as indicated in Fig. 6. The pulleys G G G are mounted to turn on nuts F F F, respectively, held stationary in or forming part of the deckle-shifter, said nuts being engaged by screw-rods H H H mounted to turn in suitable bearings in frames I I, made in sections and adj ustably held on the framework B in the vat B. The idlers G are supported on brackets F held on the deckleshifter F. (See Fig. 6.)

Now it is evident that when the cylindermold A is rotated in the usual manner in the direction of the arrow a then a traveling motion is given to the two inner runs of the deckles O C in the same direction, while the outer runs of said deckles travel in the inverse direction of said arrow a and over the pulleys G G G and the idlers G From each of the deckle-shifters F extends outwardly a segmental flange or band F formed at its outer end with an external c01- lar F on which is fitted to slide a segmental band F forming an extension or telescoping shifter provided at its inner end with an internal collar F engaging the exterior sur- Between the two colits contacting run within a segmental recess F, formed in a segmental deckle-shifter F,

with another band F which in turn is connected with a band F held stationary on the corresponding frame I or I. The several bands F F F F F can thus be telescoped one into the other when shifting the deckleshifters longitudinally on the cylinder-mold A, according to the width of the paper to be formed by the machine. The several bands F F 9, and F are provided at their upper ends with ears F loosely engaging the screwrods H and H.

Each of the screw-rods H H H is formed with a right and left hand thread, one ofwhich is engaged by the deckle'shifter carrying the deckle O and the other is engaged by the deckle-shifter carrying the deckle 0. Thus when the several screw-rods H H H are simultaneously rotated then the deckleshifters for the two deckles (J C are moved simultaneously toward or from each other to adjust the deckles on the cylinder-mold A, according to the desired width of the paper.

In order to rotate the screw-rods H H H simultaneously, we provide each of the screwrods with a sprocket-wheel K, over which passes an endless sprocket-chain K, adapted to be tightened by a tightening-pulley K journaled on a bracket K adjustably heldon the frame I. The screw-rod H is provided at one outer end with a hand-wheel H so that when the operator turns the said handwheel H and rotates the screw-rod H then the'rotary motion of the latter is transmitted simultaneously by the sprocket-chain K and the several sprocket-wheels K to the other screw-rods H H so that all the screw-rods rotate simultaneously to shift the deckle-straps toward or from each other, according to the direction in which the hand-wheel is turned.

The several telescoping bands or flanges F F F F F being provided with the rolling rubber segmental packing-rings J between their adjacent sliding surfaces and being secured to the frame B by means of the frames I I from a water-tight connection between the deckles and the sides of the frame B when the several bands 15 F F F F telescope into one another upon shifting the deckleshifters, so that the face of the cylinder-mold A is at all times surrounded and protected at those parts not occupied and used by the pulp, and consequently no waste of the pulp is liable to take place.

In order to permit the deckle-shifter to be applied to the cylinder-mold without raising the said cylinder-mold out of the vat, we prefer to make the frames I I in sections, as indicated in Fig. 3, each section having apartial hub engaging the shaft A, and the several hub-sections are fastened together by clam ping-bands I, as indicated in said figure The sections of the frames I I are provided with vertically-disposed slots for the passage of the bolts used in fastening the sections to the framework B, so that said sections can be readily adjusted in a vertical direction to compensate for the wear of the shaft A in its bearings. Thus the deckle'shifters are readily adjusted to the position of the cylindermold A to permit the inner or contacting runs of the deckles to be always in proper relation to the peripheral surface of the cylinder-.
